Korean Drama "School 2021" was definitely not like the rest of the school series dramas.

It actually feels more like the other web school dramas, with a first love romance, friendship and some school drama that was more or less boring, though the love story was cute and the love triangle interesting and it had potential. Also, the second couple often stole the thunder from the main one, especially when the latter started getting tiring and cheesy. However, the mystery wasn't there, the school politics weren't something original, and the only thing that often saved the episode was the youthful mood that was at its best.

The performances, finally, were pretty good by everyone in the cast.

So, overall, 5 out of 10.
